Rusty,
I
sure hope your right mate, I roughly weighed the centre housing, ( 31lbs or
14 kilo) a rotor ( 9lbs or 4kilo) and rotor housing ( 12lbs or 5.5 kilo)
and guess at the weight of the single shaft ( 5lbs difference or 2.2
kilo) Max all-up is approx 60lbs or 27kilo and took that off 330 lbs
(all up installation). Mine is a worst case
scenario.
What
did I forget !?
Both
Richard Sohn and myself are working on aluminium housings - I need some
desperately. However there's not a lot of savings there for the single as it
doesn't have a centre housing.
The
best case for savings with his latest development, which is now very similar to
my own, Front housings 24 lbs ( 4 lbs of wear plate) = 7
lbs of aluminium housing + 4 of wear plate = total of 11 lbs ( savings of
13 lbs); Rear housing 27lbs (4 lbs of wear plate) , 8lbs + 4pounds of wear
plate is 12 lbs ( savings of 15lbs).
Total is say approx 27/ 28 lbs as the wear
plate is still steel. So even with aluminium housings ( 330 - 90) = 240 lbs ( in
round numbers).
I would
like to know where I went wrong or what I forgot to omit as I like your figures
better Rusty. Don't tell me oil!!

You might want to check your kg to lbs conversion rates
again, mate. If you're just counting the engine, and PSRU, you could
probably save some weight by using a stock 13B and Tracy's drive
:-) You aren't making that PP adapter out of lead
are you :-)
FWIW, my
estimate is for a worst case weight of 230 lbs for the total engine
installation using stock housings. I'm pretty sure I can beat that
weight on the Kolb, but I haven't added everything up yet. If anyone
ever gets an aluminum front and rear housing to market, that will save about
25 lbs as well.
Cheers,
Rusty (no idea what I'll use for a muffler
on the single)
